I have a 2,173 single story house built in 1973 just outside Los Angeles. Summer time temparature can go up to about 110. As we recently bought this house I don't really have complete Summer time data, but am starting to prepare for the coming Summer. The area that is of concern is the attic, which runs througout the house except for 2 areas (living and family room) that goes all the way to the roof. The only ventilation that is there is 2 gable vents (at the two ends of the house) that is about 2' x 1' each and 2 wind turbines.
I have put a remote termostat to monitor the attic temparature. For example, yesterday the outside temparature went up to about 75, by afternoon/early evening attic temparature was at about 100, even though the outside temparature is about 70. Inside temparature in the house stays pretty cool (upto about 72-76) until early evening when the A/C (set at 78) kicks in.
There is some insulation already. Already have solar power installed for power generation, but I am trying to be more energy efficient.
Could putting more ventilation help? I would assume that the attic temparature should be closer to the outside temparature if properly ventilated. There is no space to put soffit vents.
Any advice would be appreciated. Thanks in advance.
